Abstract: A filter assembly includes a water filter assembly having a filter element sealingly disposed in a cartridge, and having an inlet and an outlet, the water filter assembly being substantially dripless when charged with water and disposed substantially horizontally. A manifold assembly is fluidly couplable at an inlet to a source of water to be filtered and having a filtered water outlet and having mating members for removably mating to the water filter assembly and having a mounting means attached to said manifold providing rotational travel to the water filter assembly for installation, removal and replacement of the water filter assembly. A cartridge and a water distribution manifold assembly are further included.

Abstract: A centrifugal pump for left ventricle assist includes a pump housing forming an impeller chamber with inlet and outlet passages and enclosing an impeller rotatable to move blood or other fluids through the impeller chamber, and a rotor chamber enclosing a rotor integral with the impeller and rotatable to drive the impeller. A stator is mounted outside of a rotor casing forming the rotor chamber, concentric with, radially outward of and approximately axially aligned with the rotor. The stator includes a stator frame with an annular back iron and twenty-four teeth equally spaced apart and projected radially inwardly of the back iron. Three wires, one for each of three motor phases, are wound about the back iron, each including four symmetrically arranged active segments toroidally wound about the back iron, corresponding to four poles in a permanent magnet fixed to the rotor.
